Question

For 2x - 3y = -10, when x = 4, What is the value of y?

Answer 1

2(4)-3y=-10

So 2(4)=8, then 8-3y=-10
Move the 8 to the other side by subtracting it from both sides.

Now you have -3y=-18
Divide by -3 on both sides.
Now you should get y=6

Answer 2

Do you see how I got that?

Answer 3

Yes, All you have to do is add in the x=4 to the equation?

Answer 4

Yes, simply replace the x with the 4 and then by order of operations, you clear the brackets first. So multiply 2(4) which = 8 then move the 8 to the other side of the = and then divide by your y value on both sides.

Answer 5

Had no idea it was that simple, Thank you so much!

Answer 6

No problem! I have been known to do the same thing. I get the hard ones easily and the easy ones catch me up. And I'm in college lol! Have a good night! =)
